From Salty Brine Software:
Among the fonts installed on your system are a few collections of tiny pictures and other symbols known as Symbol fonts, including Wingdings, Webdings, Symbol etc .Symbol Selector can take a chosen Wingding or Symbol and copy it to the Windows clipboard in either Rich Text Format (RTF) or as a Windows Metafile (WMF). The former would be used for word processing documents (almost all applications "understand" Rich Text); the latter would be for desktop publishing programs, although many word processors can import WMFs as well. The program also allows you to call up any font so that you can locate and copy special characters such as "Ã?Â¯Ã?Â¿Ã?Â½" into your writing. Within the Symbol Selector window, you can make the displayed font bigger or smaller or automatically return it to its "default" size.
